  • this line is divided into individual circuits leading to the consumers.
  • the cables of the individual circuits usually have conductor cross sections of 1.5 mm 2 or 2.5 mm 2 Cu. Due to the reduced cross-section of 10/16 mm 2 Cu to 1.5 / 2.5 mm 2 Cu, the individual circuits are protected against overcurrent with overcurrent protective devices (fuses or circuit breakers).
  • Overcurrent protective devices for each individual circuit.

From a power meter 2 performs a line 3 with a large conductor cross-section to a circuit manifold 4 in the form of a cabinet 5. In the cabinet. 5 the line 3 is divided into a plurality of circuits 6, which lead to the consumers 7. The lines 8 of the individual circuits 6 have smaller conductor cross sections. At the beginning of the circuit conductor 8 in the control cabinet 5, an overcurrent protection device in the form of a circuit breaker 9 is arranged in each case.

  • the invention is specified in claim 1.
  • it provides an electrical low-voltage building installation of the type mentioned, in which at least one distribution line is provided, are distributed to the branch lines to branch lines with respect to the distribution line reduced cross-section in the building.
  • the associated overcurrent protection devices distributed to the line branches or - downstream of the line branches - arranged in the branch lines.
  • the distributed overcurrent protection devices are tripped, i. Interruption of the line branch or branch line, remotely switched on again (whereby the reconnection of an overcurrent protection device is to be understood as the reconnection (ie re-interchange) of the interrupted line branch or branch line).
  • the overcurrent protection devices do not require a remote control function to interrupt their respective line branch, but perform interruption locally, i. due to own determination of an overcurrent.
  • Fig. 6 illustrated centralized arrangement of the branches and circuit breakers 9 of the prior art in a cabinet the circuit conductors 8 extend to a considerable extent in parallel. They have realized that this is not only relatively expensive, but the planning and execution of a building installation - and even more so their subsequent extension - difficult.
  • this parallelism can be avoided, such as Fig. 1 illustrated.
  • the illustrated there low-voltage building installation 11 with distributed arrangement of line branches 12 has no such parallelism.
  • From the electricity meter 2 performs a distribution line 13 of larger cross-section in the vicinity of the various consumers 7.
  • the distribution line 13 corresponds in terms of their origin and their conductor cross-section so the line 3, which conventionally connects the cabinet 4 with the power meter 2.
  • a cabinet is not present, and the distribution line 13, unlike the conventional line 3, extends far into the area to be supplied.
  • the line branches 12 are located in the vicinity of the respective consumers 7, and are therefore distributed along the distribution line 13.
  • branch lines 13 branches off in each case a branch line 14 with respect to the manifold 13 reduced conductor cross-section of the manifold 13 from.
  • the branch lines 14 thus correspond in terms of their endpoints and their conductor cross-section of the circuit conductors 8, which traditionally arise in a cabinet 4 from a division of the conductor 3.
  • a control cabinet is not present, and the branch lines 14 each originate near the consumers 7 supplied by them, ie do not run parallel to each other and extend in only a relatively short distance from the passing distribution line 13 to the respectively supplied consumers 7.
  • the associated remote-controlled overcurrent protection devices 15 are arranged distributed. In some embodiments, they are located directly on the line branches 12. In other embodiments, however, the overcurrent protection devices 15 are arranged in the branch line (after the line branches 12). If the unsecured piece of branch 14 is relatively short (eg no longer than, for example 20-30 cm), the arrangement of the overcurrent protection device 15 is not acceptable directly at the line branch 12, but only in the branch line 14. Because the resistance of the unhedged piece of the branch line 14 is then so small that in the event of a short circuit in the unhedged piece of branch line 14, the upstream fuse of the distribution line 13 will switch off.
  • the distributed overcurrent protection devices are remotely switched on after triggering, ie interruption of the branch line 12 and branch line 14, wherein the remote control signaling in Fig. 1 is illustrated by lines 16, which takes place between a control center 17 and the individual distributed overcurrent protection devices 15.
  • the overcurrent protection devices 15 do not require a remote control function to interrupt their respective line branch 12 or branch line 14, respectively, but cause the interruption to be local, i. due to own determination of an overcurrent. Even in the event of a failure or functional restriction of the remote control, it is thus ensured that e.g. in the case of a short circuit in a branch line 14, the associated overcurrent protection device 15 separates the branch line 14 from the distribution line 13 and thus terminates the short-circuit current flow. Only the reconnection would be affected by a failure of the remote control.
  • the electrical low-voltage building installation thus refers to how beside the Fig. 1 also the Fig. 2 and 4
  • it refers to the line installation after the last electricity meter before the consumers 7.
  • the distributed overcurrent protection devices 15 are not arranged in a distribution cabinet 5, but are distributed along the distribution line 13 is arranged, which is passed in the vicinity of the consumer 7 to this.
  • the line branches 12 and the associated overcurrent protection devices 15 are distributed along the distribution line 13, resulting in a minimum overall line length for the distribution line 13 and branch lines 14.
  • the distributed overcurrent protection devices 15 are housed in hollow ceilings, hollow floors, hollow walls, cable ducts and / or flush-mounted boxes.
  • control center 6 For central control, ie in particular for reconnecting the distributed overcurrent protection devices 15, the control center 6, which in the Figures 2 and 3 Also referred to as "control center" is.
  • the distributed overcurrent protection devices 15 are arranged to transmit their current switching state to the control center 6.
  • the control center 17 has a user interface for the central command input for the remote control of the distributed overcurrent protection devices 15, for example in the form of a keypad 18 a with key sensors.
  • it may also have a user interface for visualizing the state of the distributed overcurrent protection devices 15, eg a display 18b in the form of a screen or an LED display.
  • the signals for remote control of the overcurrent protection devices 15 and possibly to return their switching state are in the embodiments of the Fig. 2 and 3 transmitted via a data cable to and from the overcurrent protection devices 15 (another embodiment with wireless signal transmission will be discussed below Fig. 4 illustrated).
  • a data cabling in which each overcurrent protection device 15 to be controlled is connected to the control center 17 with its own data line, so that the addressing of the individual overcurrent protection devices 15 could take place solely via the choice of the relevant data line.
  • a data bus 19 is provided for this purpose, with which the control center 17 and the various overcurrent protection devices 15 are connected.
  • the data bus 19 serves not only for communication with the circuit breakers, but also with actuators 20 for the consumers 7.
  • the actuators 20 are, for example, remotely controlled on-off switches, dimmers, climate control, load control, lighting control, sunblind control, air conditioning, emergency equipment control etc. can serve.
  • the consumers 7 are electrically connected, for example, via branch lines 26 and the actuators 20 to the branch line 14. Data obtained with sensors can also flow in the other direction via the data bus 19.

  • the overcurrent protection devices 15 are coupled to the data bus 19 with bus couplers 21. The same applies to the control center 17 and the actuators 20.
  • control center 17, overcurrent protection devices 15, actuators 20 takes place by specifying the addresses of the bus elements in the data units given to the bus (often called "telegrams" in building installation bus systems).
  • the signals for remote control of the overcurrent protection devices 15 and possibly to return their switching state, for example, in the form of such telegrams on the data bus 19 are transmitted to and from the overcurrent protection devices 15.

  • the data bus 19 runs parallel to the distribution line 13, for the purpose of coupling with the overcurrent protection devices 15, which are arranged distributed along the distribution line 13.

  • the overcurrent protection devices 15 have in the embodiments of Fig. 2-5 in each case a circuit breaker 22 and an electric drive 23 for their remote-controlled reclosing.
  • the circuit breakers 22 are adapted to detect an overcurrent in their associated branch line 14 and to disconnect the branch line 14 associated with them upon detection of an overcurrent under load. You do not need any control signal from the data bus 19 or similar, and also no external auxiliary power; Rather, they have stored the necessary energy for separation itself, for example in the form of elastic deformation energy in a tensioned at continuously connected line spring, which is relaxed to disconnect the line 14.
  • the electric drive 23 is adapted to bring its assigned from the tripped state (in which the branch line 14 is separated) back into the on state (in which the branch line 14 is turned on again), namely remotely controlled by the bus coupler 21 from the data bus 19.

  • the electric drive 23 is connected via a connecting line 25 to the distribution line 13 or the branch line 14 above the separation point of the circuit breaker 22, and thus receives its external energy from the power network.
  • the power supply of the electric drive 23 takes place from the data bus 19; the connecting line 25 is then omitted.
  • the power supply from the data bus 19 can be done for example by a small DC voltage (eg 15 V), which is impressed on the data bus 19.
  • Such impressed small DC voltage also serves as a supply voltage for bus electronics (ie for the bus coupler 21) and possibly for powering sensors and actuators 20 and coupled to the bus 19 sensors.
  • the circuit breaker 22 is a circuit breaker designed for manual, but not remote, reclosing as commonly used in circuit breakers in conventional centralized building installations of the type of Fig. 6 is used.

  • the overcurrent protection device 15 has a feedback function: The current state of the circuit breaker (that is, whether it is triggered or turned on) is routed via the bus coupler 21 and the data bus 19 as a telegram to the control center 17 and possibly displayed there on the display 18b , As donors for the current state serve as auxiliary contacts of the circuit breaker 22nd

  • the measured differential current can also be reported back to the control center continuously.
  • the invention is in the context of building automation with bus systems.
  • Building automation with bus systems basically allows the cabling of a building without a centrally located control cabinet.
  • Large systems with distributed intelligence can be set up and further supplemented at any time. Big advantage is the simpler cost-effective cabling, the actuators are not located in a central office of which all consumers are controlled (with separate cable management) but can be placed directly in the vicinity of the consumer. All actuators and consumers can be attached to a cable loop. If this potential is used deliberately, it can save a considerable amount of money and there are also cost-effective ways to expand the system.
  • this basic idea of the bus systems is considerably disturbed by the arrangement of the protective devices in the prior art. Overcurrent and short circuit are selectively protected, where the conductor cross section (the current carrying capacity) changes.
  • the fuses or circuit breakers must be easy to reach in the prior art because of the operation, so you put these in turn in a cabinet, from which the individual circuits are branched off. From this necessity arises again a central system.
  • the advantages of distributed intelligence can therefore be used in the prior art only with unchanged cross-section and load capacity - consequently limited.
  • the invention eliminates these disadvantages and allows the benefits of fully distributed intelligence to be realized without compromising the original security features.
  • the idea is to place the overcurrent relays on the cable, on the nodes (junction with a different cross-section) and control the operation by remote control. This takes place as a telegram (command) via the data cable (bus).
  • the individual protection devices, automatic circuit breakers can be reached via the bus line at its own address.
  • Turning on and off happens e.g. via the button sensor, which is connected via the bus coupler to the data cable and sends the switching commands as telegrams to the programmed address.
  • the telegram triggers the movement for the direct switching of the automatic circuit breaker in the mechanical actuating unit. Switching on and off is thus done by pressing a button.
  • the current state is in turn directed by the auxiliary contacts of the circuit breakers via the data cable as a telegram to the visualization.
  • the circuit breaker will switch off the circuit immediately and send the status as a telegram to the visualization.
  • a Bus coupler can be connected to the data cable.
  • This unit only needs one data cable feeder and no further cabling.
  • the power distribution is completely detached from the control and monitoring unit, the wiring can be decentralized and very economical.
  • the unit is - like the overall system - expandable at any time and even without additional cabling.
  • the circuit breaker can always be placed at the branch. (New branches are possible at any time).
  • the system (with corresponding hardware and software adaptations) can be used with all bus systems (KNX, LON, CAN, ).
  • the system can be equipped with any commercially available circuit breaker and sensors as well as visualization (LED-s or screen). (It may make sense to adapt between mechanical actuator and circuit breaker). In this case, proven and approved devices can be selected for the safety-relevant elements.
  • the invention is equipped with circuit breakers with FI (residual current device - switch). In this case, the turn-off will be switched off not only in case of overload but also in the case of unauthorized leakage current.
  • FI residual current device - switch
  • This variant can also be visualized (corresponding programming, additional LED).
  • An additional sensor key can be used for the periodic check of the FI switch.
  • the central control unit can be equipped with an additional key-operated switch. By turning and removing the key, it is blocked by pressing a key (software), the system can not be switched on accidentally.
  • protective relays, mechanical actuation and bus couplers will be placed in the same housing. As a result, the size can be significantly reduced.
  • bus system to remotely set the tripping current and the tripping / delay times individually programmed.
  • the parameterization of the circuit breakers can be carried out via software.
  • a special further embodiment variant is the data transmission via infrared radiation, without data cable connection. In this case, however, the transmitters and receivers - additional components - must be placed accordingly. (Free sight)
